evolve: don't update wdir when --dry-run is given (issue6669)

What _cleanup() should've been called, perhaps, is _update(). Because it
updates working copy to either headnode or a successor of startnode. And yes,
it performs an update even when shouldupdate is False. So when --dry-run is
given, we should simply avoid calling _cleanup().
